Aberg choked on the final day at Wentworth BMW when he had the lead and shot 76, he also choked in a playoff for Sanderson Farms on PGAT against a weak field as well, so pressure clearly does affect him. Luckily at the Ryder Cup he had great team mates to back him up.
Koepka had to boat race Aberg as revenge for how Hovland & Aberg boat raced Brooks & Scottie the day before. It was strange that Captain Zach Johnson decided to play an off form JT in more team matches than the recent PGA major winner and Masters runner up Brooks.....poor decision.
